The present invention relates to a communication technique, which is a convergence of IoT technology and 5G communication system for supporting higher data transmission rate than 4G system, and a system for same. The present invention can be applied to smart services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security-and safety-related services and the like) on the basis of 5G communication technology and IoT-related technology. The present invention provides a beamforming antenna module comprising: a beamforming antenna for radiating a beam in a particular direction, a first lens positioned a preset first distance away from a beam radiation surface of the beamforming antenna and for varying the phase of a beam radiated by means of the beamforming antenna; and a second lens positioned a preset second distance away from a beam radiation surface of the first lens and for varying the phase of the beam radiated by means of the beamforming antenna.
